Drayton LWC1 Wiring Centre Wiring guide

Drayton LWC1 Wiring Centre

INTRODUCTION

Wiring centres, designed to simplify wiring installations and circuit checking, lose some of their value if they are not in themselves easy to understand and use. The Drayton LWC1 wiring centre has been introduced to meet this requirement.
The LWC1 is suited to all popular central heating and hot water systems, with adequate wiring space, terminals and cable access points. Its use will save the installer time and uncertainty, both at the time of installation or in any subsequent checking.
This wiring guide covers, in a superb easy-to-understand manner, the main systems in popular use. It assumes that the installer can identify from the boiler, pump and controls literature to hand, the elementary mains supply and switch terminals or leads. The result is a handy pocket-sized wiring guide which does not suffer from superfluous detail and which makes the busy installer’s job that much easier.
Although Drayton are not consultants and cannot offer to design systems, they will readily provide advice on the use of the LWC1 in any system not covered.
NB: All wiring must be to latest I.E.E. standards and carried out by a competent, qualified installer.
